Abstract
Use of the surface presentation level of binders (e.g., antibodies, receptors) on cultured higher eukaryotic cells in vitro as a predictive indicator of developability characteristics, e.g., solubility, of the binders. Display libraries of higher eukaryotic cells, e.g., mammalian cells, adapted for use in screening surface-displayed binders for developability and affinity of target binding. High-throughput screening of display libraries with in-built selection for developability including binder solubility, capability to be formulated at high concentrations, low propensity for non-specific binding, and half-life. Enrichment of populations of binders for developability characteristics and/or other qualities such as target binding and affinity, by controlling cell surface presentation of binders from an inducible promoter operably linked to binder-encoding DNA.
